How to Take Scratches Out of Corian Countertops

Julie SlezakUpdated April 17, 2017

Corian countertops are a DuPont product made out of an acrylic polymer. Because they are man-made, they come in a wide variety of colours and can be found at many home improvement stores. Unlike natural stone countertops, Corian is non-porous which limits the growth of mildew and bacteria. They are solid all the way through and built to last. This means you don't need to worry about peeling like you get with laminate countertops. Corian resists fading, stains, scratches and heat. If scratches or cuts do appear, however, you can easily repair them yourself.

Squeeze out a mild abrasive liquid cleanser onto a damp sponge.

Rub in a circular motion over the scratched area (this also helps with blotchiness). Change direction to front to back and then side to side.

Rinse area with water and wipe completely dry. If the scratch is still visible, repeat above steps or proceed to next section.

Wash the area where the scratch is located and let completely dry.

Sand surface gently with 180 or 220 grit fine sandpaper for matt/satin finish and 400 grit for semi-gloss finish. Move in straight lines following the direction of the scratch then change direction ninety degrees and rub in a straight line. Don't press down too hard or you could deepen the scratch. Increase your rubbing area in order to blend the affected surface with the rest of the countertop.

Wipe surface with a dry rag. Use a non-abrasive liquid cleanser and a green Scotch-Brite pad to restore finish.

Purchase or borrow a low-speed polisher with a wool pad. 1500 to 2000 rpm is appropriate for this project. White polishing compound will also be needed.

Wash the area where the scratch is located and let completely dry.

Sand surface gently with 400 grit sandpaper. Move in straight lines following the direction of the scratch then change direction ninety degrees and rub in a straight line. Don't press down too hard or you could deepen the scratch. Increase your rubbing area in order to blend the affected surface with the rest of the countertop.

Wipe surface with a dry rag and move on to 600 grit sandpaper. Once again, move in straight lines, widening your rubbing area to help blend surfaces.

Wipe surface with a dry rag. Buff area with low-speed polisher between 1500 to 2000 RPM and white polishing compound. Wipe down and restore finish with a countertop wax.
